There's a couple ways to do it, but pump(s) will need to be involved. Roughly speaking you can figure 0.5 psi drop for every vertical foot of rise. So, at about half way up your hill, the pressure will have fallen from 75 psi to near 0. This doesn't include any frictional losses. You could do something with a couple of booster pumps along the way to get you there. Another option could involve cisterns and submersible pumps. Either way, you are looking at a lot of trenching for pipe and wiring. Also, the long distances will not only involve sizing the piping (due to frictional losses), the wiring for the pumps will also have to be sized due to the voltage drop over that distance.
Once you have a general idea of the design, you can start sizing the pumps, wiring, piping, etc. You will also have to think above freeze protection for each pumping station (depending on design).
